Generator Model: 21429783 high-frequency machines and machine-frequency comparison: small size, light weight, high efficiency (low operating costs), low noise, suitable for office space DSE, cost-effective (the same power, low price ), space, the environment is small, relatively speaking, high-frequency charger susceptible to copiers, impact (SPIKE) laser printers and motors cause and transient response (TRANSIENT), due to the frequency machine to the mains transformer and load isolation DSE5120, mains under harsh environment, frequency machine to provide a more secure and reliable than the high-frequency protection function, in some cases, such as medical and other DSE7110, require isolation device charger, therefore, industrial, medical and transportation applications DSE7320, frequency machine is a better choice to select between the two trade-offs depending on the installation environment, load conditions charging customers Model: 3634778 battery fast charging theory originated from two 60 Shi Ji mid-1980s Americans Maas (JAMas) JAs charging curve (Figure 1, is Ma Situ) It started with small capacity of lead-acid batteries obtained experimental curve, and grouped into three laws Maas, The main point is: it is based on their storage battery charge acceptance rate and accept the charge, to the value of the charging curve that will extend the charging time low, but more than the value of the charging curve does not only shorten the charging time, the opposite will be increased pressure and temperature battery Thus Corollary: Only build a larger battery charge acceptance rate while at the same time can inhibit battery gassing conditions, adequate power party can in a short period of time DSE7210 | Zhongxin Electrical and Mechanical (certified) | DSE by City South City Zhongxin Electrical and Mechanical Services Department provides. Dongguan City, South City Zhongxin Electrical and Mechanical Services Department (zhongxin888.net.cn) is Dongguan, industrial products leader, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
